[0013] The processing method comprises the following steps: Step 1: Primary filtration: Sewage enters the primary filter tank from the sewage collection port and is filtered for large particles of impurities by the rotating No. 1 filter cartridge. The servo motor drives the drive rod to rotate, which drives the drive gear to rotate synchronously. The drive gear rotates, which drives the teeth to rotate, thereby driving the rotating ring and the No. 1 filter cartridge to rotate. The rotation of the No. 1 filter cartridge generates centrifugal force, which drives the water flow radially.

The double-cylinder differential rotates in the opposite direction to form a high shear flow field to peel off attached pollutants. At the same time, the rotation of the No. 2 filter cartridge 9 can perform a centrifugal acceleration motion on the sewage entering the interior, thereby accelerating the sewage filtration.

[0022] As a preferred embodiment, the bottom end of the linkage shaft 12 is fixedly connected to a cleaning roller 14, the outer wall of the cleaning roller 14 is connected to a cleaning brush 15, the inner wall of the No. 2 filter cartridge 9 is arranged and fixedly connected with a guide plate 16, the bottom end of the No. 1 filter cartridge 4 is fixedly connected to a bottom plate 17, a cleaning door 18 is embedded in the center of the bottom plate 17, the cleaning door 18 and the bottom plate 17 are fixedly connected by a snap fastener, an annular groove 19 is provided on the top outer wall of the cleaning door 18, the bottom end of the No. 2 filter cartridge 9 is embedded in the annular groove 19, and the No. 2 filter cartridge 9 is slidably connected to the annular groove 19, wherein the linkage gear 13 can drive the linkage shaft 12 to rotate while rotating. The linkage shaft 12 rotates synchronously to drive the cleaning roller 14 to rotate, and the cleaning roller 14 rotates to drive the surface cleaning brush 15 to rotate. The cleaning brush 15 can clean the No. 2 filter cartridge 9 and the No. 1 filter cartridge 4 synchronously, and the bristles 15 physically remove the blockages in the hole, and the flux maintenance rate is improved. The guide plate 16 extends the water flow path, improves the impurity capture rate, and at the same time induces vortex to enhance centrifugal separation. The water flow can be accelerated to filter and filter cleaning by a single power, which improves the energy saving of the device. The bottom plate 17 plays a connecting role, and the impurities remaining after filtration will accumulate on its surface. The impurities can be removed and cleaned by opening the cleaning door 18.

When the No. 1 filter cartridge 4 rotates, the connecting rod 20 drives the stirring rod 21 to disturb the bottom of the pool, the pH detection probe 22 monitors the water quality in real time, and triggers the automatic dosing bottle 23 to dosing. The stirring rod 21 prevents precipitation at the bottom of the pool and promotes the diffusion of the agent, thereby avoiding uneven dosage due to too little or too much dosage.

The vibration mechanism 24 includes a linkage ring groove 25, a tooth groove 26, a fixed cylinder 27, a push rod 28, a spring 29 and a ball 30.

When it moves out of the oblique tooth groove 26, the spring 29 rebounds and pushes the ball 30 to hit the tooth groove 26, generating high-frequency micro-vibration, thereby effectively shaking off deep blockages.

The four-stage treatment realizes the step-by-step removal of pollutants. The electric drive wheel 37 is controlled to move along the guide rail 35 to drive the movable frame 36 to reciprocate horizontally. At the same time, the height of the scraper 39 is adjusted in conjunction with the electric telescopic rod 38, so that the movable frame 36 moves to drive the scraper 39 to push the scum into the sewage collecting tank 41 for collection. The low-voltage DC electrode net 40 at the bottom releases a weak electric field when scraping the scum, which promotes the secondary adsorption of bubbles and flocs.

The synchronous toothed belt 49 is a double-sided tooth type, and the driving rack 43 is meshed with the synchronous toothed belt 49. Among them, the aerator 42 is a structure of the prior art. The structure can generate bubbles at the bottom of the flotation tank 32 to achieve flocculation of bubbles and impurities. When the mobile frame 36 moves, it drives the driving rack 43 to move synchronously. The driving rack 43 engages the synchronous toothed belt 49 to drive the synchronous toothed belt 49 to rotate. The synchronous toothed belt 49 drives the synchronous gear 48 to rotate, thereby driving the rotating rod 431 to rotate. The rotation of the rotating rod 431 transmits power to the fan shaft 45 through the bevel gear 47 to rotate. The isolation box 44 is a sealing mechanism to prevent liquid from entering. The rotation of the fan shaft 45 drives the spiral fan 46 to rotate at the bottom of the pool. At the same time, the spiral fan 46 is distributed on one side of the exhaust end of the aerator 42. The rotating spiral fan 46 can break up the larger bubbles generated by the aerator 42 and enhance the collision between the dissolved air and the flocs, thereby improving the bubble utilization rate. The breaking work is driven by the electric drive wheel 37 to drive the auxiliary frame 421, eliminating the need for an independent motor.

[0027] As a preferred embodiment, the processing method comprises the following steps: Step 1: Primary filtration: Sewage enters the primary filter tank 1 from the sewage collection port 201 and is filtered for large particles of impurities by the rotating filter cartridge 4. The servo motor 8 drives the drive rod 6 to rotate, which drives the drive gear 7 to rotate synchronously. The rotation of the gear 7 drives the teeth 5 to rotate, thereby driving the rotating ring 3 and the filter cartridge 4 to rotate. The rotation of the filter cartridge 4 generates centrifugal force, which drives the water flow radially. The filter cartridge 9 rotates in the opposite direction through the differential speed of the inner and outer gear rings 11, 10 and the linkage gear 13, forming a shear flow field to prevent blockage and simultaneously stripping away attached pollutants. Step 2: The filter cartridges are self-cleaning. When the No. 1 filter cartridge 4 rotates, the internal gear ring 11 on its top drives the linkage gear 13 to drive the linkage shaft 12 to rotate. The bottom end of the linkage shaft 12 drives the cleaning roller 14 to rotate. The rotation of the cleaning roller 14 drives the cleaning brush 15 to clean the No. 1 filter cartridge 4 and the No. 2 filter cartridge 9 synchronously to prevent the holes from being blocked. Step 3: When the first filter cartridge 4 rotates, the beveled tooth groove 26 of the linkage ring groove 25 periodically squeezes the ball 30, the push rod 28 retreats and compresses the spring 29, and the spring 29 rebounds and pushes the ball 30 to hit the linkage ring groove 25, generating high-frequency micro-vibration. The vibration wave is transmitted to the first filter cartridge 4, shaking off deep blockages; Step 4: Multiple treatment. The effluent from the primary filter tank 1 is driven by the liquid pump 34 through the drainage pipe 33 and enters the sedimentation tank 31, the flotation tank 32 and the fine filter tank 321 in sequence, thereby achieving multiple filtration treatment of the spunlace non-woven wastewater. The four-stage treatment realizes the cascade removal of pollutants.

[0028] The working process of the present application is as follows: first, sewage enters the primary filter tank 1 from the sewage collection port 201, and large particles of impurities are filtered through the rotating No. 1 filter cartridge 4. The servo motor 8 drives the drive rod 6 to rotate and drives the drive gear 7 to rotate synchronously. The rotation of the gear 7 drives the teeth 5 to rotate, thereby driving the rotating ring 3 and the No. 1 filter cartridge 4 to rotate. The No. 1 filter cartridge 4 rotates to generate centrifugal force, which promotes the radial movement of the water flow. The No. 2 filter cartridge 9 rotates in the opposite direction at a differential speed through the inner gear ring 11, the outer gear ring 10 and the linkage gear 13 to form a shear flow field to prevent blocking and at the same time peel off the attached pollutants. The linkage gear 13 can drive the linkage shaft 12 to rotate while rotating. The rotation of the linkage shaft 12 synchronously drives the cleaning roller 14 to rotate. The rotation of the cleaning roller 14 drives the surface cleaning brush 15 to rotate. The cleaning brush 15 can synchronously clean the No. 2 filter cartridge 9 and the No. 1 filter cartridge 4. The hair 15 physically removes the blockage in the hole, and the flux maintenance rate is improved. The guide plate 16 extends the water flow path, improves the impurity capture rate, and at the same time induces vortex to enhance centrifugal separation. The water flow acceleration filtration and filtration cleaning can be achieved through a single power, which improves the energy saving of the device. The bottom plate 17 plays a connecting role. The impurities remaining after filtration will accumulate on its surface. By opening the cleaning door 18, the impurities can be removed and cleaned. When the No. 1 filter cartridge 4 rotates, it can drive the linkage ring groove 25 to rotate synchronously. The rotation of the linkage ring groove 25 causes the ball 30 to change its position in the groove, so that the oblique tooth groove 26 of the linkage ring groove 25 periodically squeezes the ball 30, and the push rod 28 is forced to retreat and compress the spring 29. When it moves out of the oblique tooth groove 26, the spring 29 rebounds and pushes the ball 30 to hit the tooth groove 26, generating high-frequency micro-vibration, thereby effectively shaking off deep blockages; The effluent from the primary filter 1 is driven by the liquid pump 34 through the drain pipe 33 and enters the sedimentation tank 31, the flotation tank 32 and the fine filter tank 321 in sequence, thereby realizing multiple filtration treatment of the spunlace non-woven wastewater. The four-stage treatment realizes the step-by-step removal of pollutants. The electric drive wheel 37 is controlled to move along the guide rail 35 to drive the movable frame 36 to reciprocate horizontally. At the same time, the electric telescopic rod 38 is used to adjust the height of the scraper 39, so that the movable frame 36 moves and drives the scraper 39 to push the scum into the sump 41 for collection. The low-voltage DC electrode mesh 40 at the bottom releases a weak electric field when scraping the scum, which promotes the secondary adsorption of bubbles and flocs. When the movable frame 36 moves, it drives the drive rack 43 to move synchronously. The drive rack 43 engages the synchronous toothed belt 49, thereby driving the synchronous toothed belt 49 to move. The synchronous toothed belt 49 drives the synchronous gear 48 to rotate, thereby driving the rotating rod 431 to rotate. The rotating rod 431 rotates and transmits power to the fan shaft 45 through the bevel gear 47. The isolation box 44 is a sealing mechanism to prevent liquid from entering. The rotation of the fan shaft 45 drives the spiral fan 46 to rotate at the bottom of the pool. At the same time, the spiral fan 46 is distributed on one side of the exhaust end of the aerator 42. The rotating spiral fan 46 can break up the larger bubbles generated by the aerator 42 to enhance the collision between the dissolved air and the flocs, thereby improving the bubble utilization rate. The breaking work is driven by the electric drive wheel 37 to drive the auxiliary frame 421, eliminating the need for an independent motor. The above is the working principle of this energy-saving spunlace non-woven fabric multi-filtration water treatment device and its treatment method.

A treatment method for an energy-saving spunlace nonwoven fabric multiple-filtration water treatment device, using the energy-saving spunlace nonwoven fabric multiple-filtration water treatment device according to any one of claims 1 to 9, characterized in that: The processing method comprises the following steps: Step 1: Primary filtration. Sewage enters the primary filter tank (1) from the sewage collection port (201), and is filtered through the rotating filter cartridge (4) to filter large particles of impurities. The servo motor (8) drives the driving rod (6) to rotate and drives the driving gear (7) to rotate synchronously. The driving gear (7) rotates and drives the teeth (5) to rotate, thereby driving the rotating ring (3) and the filter cartridge (4) to rotate. The rotation of the filter cartridge (4) generates centrifugal force, which drives the water flow to move radially. The filter cartridge (9) rotates in the opposite direction through the inner gear ring (11), the outer gear ring (10) and the linkage gear (13), forming a shear flow field to prevent blocking and stripping attached pollutants at the same time. Step 2: The filter cartridge self-cleans. When the No. 1 filter cartridge (4) rotates, the inner gear ring (11) on its top drives the linkage gear (13) to drive the linkage shaft (12) to rotate. The bottom end of the linkage shaft (12) drives the cleaning roller (14) to rotate. The rotation of the cleaning roller (14) drives the cleaning brush (15) to clean the No. 1 filter cartridge (4) and the No. 2 filter cartridge (9) synchronously to prevent the holes from being blocked. Step 3: Vibration anti-blocking reinforcement. When the No. 1 filter cartridge (4) rotates, the beveled tooth groove (26) of the linkage ring groove (25) periodically squeezes the ball (30). The push rod (28) retreats and compresses the spring (29). The spring (29) rebounds and pushes the ball (30) to hit the linkage ring groove (25), generating high-frequency micro-vibration. The vibration wave is transmitted to the No. 1 filter cartridge (4), shaking off deep blockages. Step 4: Multiple treatment. The effluent from the primary filter (1) is driven by a liquid pump (34) through a discharge pipe (33) and enters the sedimentation tank (31), the flotation tank (32) and the fine filter tank (321) in sequence, thereby achieving multiple filtration treatment of the spunlace non-woven fabric wastewater. The four-stage treatment realizes the cascade removal of pollutants.
